„ Verify that your fireplace is compatible with your available gas
type. (Natural Gas or Propane shown by "N" or "L" in your
model number
„ If gas type is not compatible, contact your local Montigo
representative.
„ Conversion kits must be installed by a qualified service technician.
Note: After gas line is connected, each appliance connection,
valve and valve train must be checked while under normal
operating pressure with either a liquid solution, or leak
detection device, to locate any source of leak. Tighten any
areas where bubbling appears or leak is detected until
bubbling stops completely or leak is no longer detected.
DO NOT use a flame of any kind to test for leaks.
WARNING!
When pressure testing the fireplace, Gas line, and input system
follow the appropriate local codes or your area. DO NOT connect
the fireplace to pressures in excess of 1/2lb. This will damage the
gas control valve.

„ See Figure 21 below for location of gas line access.
„ Flexible gas connectors must not exceed 3 feet in length, unless
allowable within local regulations.
„ Connect incoming gas line to the 1/2"or 3/8" gas inlet port.
„ Purge all air out of gas line.
„ Check appliance connection, valve and valve train under normal
operating pressure with a commercially available leak check
solution.
„ DO NOT USE A FLAME OF ANY KIND TO TEST FOR LEAKS.

Section 5-2: GAS PRESSURE
Section 5-3: GAS CONNECTION
„ Optimum appliance performance requires proper input pressures.
„ Gas line sizing requirements will be determined in ANSI Z223.1
National Fuel Gas Code in the USA and CAN/CGA B149 in
Canada.
Pressure requirements are:
„ The manifold outlet pressure is set from the factory to the
appropriate pressure but should be verified.
„ To check pressures, control valves have a provision to remove
a 1/8” N.PT. plug to be fitted with a hose barb.
„ Montigo requires a service shut off valve be located in an
accessible location to isolate the gas supply.
„ Only install gas shut-off valves approved for use by the state,
province, or other governing body in which the fireplace is being
installed.
WARNING:
An inspection of the explosion relief flappers and door
MUST be made prior to lighting the fireplace. A faulty seal
on the door gasket and/or explosion ports will result in
products of combustion leaking into the living space and
may result in carbon monoxide poisoning.
WARNING
When installing the fireplace - gas lines, fittings,
accessories or any other objects cannot impede the
proper movement of the door buckles.
